If the next print statement printed a carriage return, would be set to 0 and the space would never be printed. The space character wasn’t really printed until something else got printed on the same line.

Instead of printing a space, Python 2 would set to 1. The print statement in Python 2 used a now-deprecated attribute called softspace. (Technically, it’s a little more complicated than that. In Python 2, if you ended a print statement with a comma, it would print the values separated by spaces, then print a trailing space, then stop without printing a carriage return.

To print two values separated by a space, call print() with two arguments.

To print a single value, call print() with one argument.

To print a blank line, call print() without any arguments.

Whatever you want to print, pass it to print() like any other function. Whatever you wanted to print simply followed the print keyword. This appendix documents what it can fix automatically.

Case study: porting chardet to Python 3 describes how to run the 2to3 script, then shows some things it can’t fix automatically. But don’t despair! To help with this transition, Python 3 comes with a utility script called 2to3, which takes your actual Python 2 source code as input and auto-converts as much as it can to Python 3.

So much has changed between Python 2 and Python 3, there are vanishingly few programs that will run unmodified under both. You are here: Home ‣ Dive Into Python 3 ‣ĭifficulty level: ♦♦♦♦♦ Porting Code to Python 3 with 2to3
